[v2,0/5] kvm: selftest: add dirty logging test

Message

v2:
- tune the parameters a bit (32 loops, 10ms interval) to let the test
  run ~1sec [Paolo]
- pass in extra mem pages in vm_create_default() [Paolo]
- add simple statistics on bits checked
- allow to specify parameters via argc/argv
- free bmap_track, which I forgot; rename to host_bmap_track

Add a simple test for existing dirty logging facility.

Please have a look, thanks.

  tools: introduce test_and_clear_bit
  kvm: selftest: unify the guest port macros
  kvm: selftest: include the tools headers
  kvm: selftest: pass in extra memory when create vm

Queued, only renaming the test to dirty_log_test.c.
